Specification of Letters Patent.

1912. seria1No. 690,773.

Application filed April 15,

wise provided with a corresponding dividing rib 10.

Thev frogs are adapted upon each rail as shown, tion that the base ofthe V containing the entrances La and 5a rests upon one of the cross.ties 11 from which it is inclined to the horizontal rising gradually tothe level of the ball of the rail, the narrow forward portion of thefrog being supported upon the legs 12.

The operation of the device will be obvious to one skilled in the art.

The two frog members are not counter parts one ofthe other but arerather coinplementary and they are arranged in such manner that theguard ribs 3 shall be within the rails and the guard ribs 2 without thesame, in which position the merging point of the grooves in each casewill be just within flange of the wheel guided from either d1- rectionwill drop to its proper position upon the inner side of the rail ball.Whether the wheels are derailed upon one side of the track or the otherthey will, when drawn forward, engage with the flaring entrances a and5a and will be deflected by said grooves and directed by the guard ribs2 and 3 laterally to the proper position relative to the rails, whencontinued further movement will bring the wheels upon the rails inproper relation thereto.

Having thus described claim:

1. A rerailing frog comprising a truncated V-shaped casting inclined tothe horizontal and having upon its upper face marginal guard ribsextending from the base upwardly toward the truncated end of the kV, andalso provided substantially parallel to one of the ribs with a wheeliiange receiving groove and upon the opposite side at an oblique angleto the guard rib with a similar wheel fiange receiving groove merginginto the rst groove at the apex, the twoflange receiving grooves mergingat a point just inside the rail, the lower portions of the groove beingwidened laterally to afford a flaring entrance thereto, said castingbeing provided o-n its lower face along its axis with a rail receivinggroove, and upon its upper face above the rail receiving groove with acorresponding axial dividing rib.

2. A rerailing frog comprising a truncated To all whom t may concern Beit known that I, CHARLES HILL GAM- BILL, a citizen of the United States,residing at Nashville, in the county of Davidson and Stat-e ofTennessee, have invented certain new and useful Improvements in Car-Rerailing Frogs, 'of which the following is a specification, referencebeing had to the accompanying drawings.

This invention relates to rerailing frogs by means of which the wheelsof railway cars and engines maybe expeditiously and accurately guidedupon the rails when they have been derailed from any cause.

The object of the invention is the provision of a portable frog of thischaracter which can be manufactured at a minimum of cost and will bedurable and effective in its operation.

The invention as hereinafter particularly claimed will be readilyunderstood from the accompanying drawings taken in connection with thedetailed description of the same which follows:

In the drawings: Figure 1 is a top plan. view of a pair of frogs inoperative relation to the rails; Fig. 2 is a side elevation of the same;Fig. 3 is a transverse vertical section on the line 3-3 of Fig. 1; andFig. 4t is a similar section on the line 4--4 of Fig. 1

My improved rerailing frog comprises essentially a castingl having theform in top plan of a truncated V. The upper face of the .frog isslightly inclined to form an approach and is provided with marginalguard ribs 2 and 3, which extend from the broad base of the V to thetruncated apex of the same. The upper face of the frog is providedsubstantially parallel to the guard rib 3 with a flange receiving groove4c and at an oblique angle to the guard rib 2 with a flange receivinggroove 5. These two grooves converge toward the apex of the V and mergeat the point 6, which lies at that side of the axis of the V which isbetween the rails 7 and 8 of the track. The lower portions of thegrooves 4 and 5 are widened laterally at 4a and 5a to afford a flaringentrance thereto, the entrance La when the frog is in operative positionbeing between the rails and the entrance 5a exterior thereto.

The frog is provided upon its lower face with a rail receiving groove 9which corresponds substantially with the axis of the frog, the upperface of the frog being liketo be placed one and in such positheinvention, l

the rails at the point where the V-shaped casting provided with aninclined said Wheel flange grooves merging at the approach, the upperface thereof having apex of the truncated V-shaped casting and wheelflange grooves, the outer wall of one the lower face of the said castingbeing pro- 15 groove being parallel with the inner edge of vided with arail receiving groove, sub-- the fro-g, the outer wall of the othergroove stantially as described.

being at an oblique angle to the outer edge In testimony whereof Ihereunto alliX my of the frog, one end of the inner walls of signaturein the presence of two witnesses.

said grooves being substantially parallel `l 1 with the rails, theopposite ends thereof each CHARLES HILL (,IAMBILL' being parallel with`the .opposite wall of said Witnesses: groove, guard ribs extendingupwardly C. W. CASE, along the marginal edges of the east-ing, the C. W.JACKSON.
